Escape indoor navigation system used for guests based on building structure chart and fire-fighting communication system

Abstract

The invention discloses an escape indoor navigation system used for guests based on a building structure chart and a fire-fighting communication system. The method comprises the following steps: storing the building structure chart, arranging a hand-held terminal and activating the hand-held terminal, performing real-time positioning and dynamic calibration on escape people, wherein the dynamic calibration of the position of the escape people employs a position coordinate of a RFID label collected by the hand-held terminal of the escape people, or a mapping relation of numbers of floors, roomsor stairs of the escape people in an on-site building and a corresponding point on the structure chart, or an address code of a smoke alarm which is nearest to the escape people and automatically obtained, so that the current position coordinate of the escape staff can be determined. A master control system integrates the information collected by several terminals, and then the building structurechart is combined, and graphical display is realized through a display module, and condition in the building can be better and conveniently understood for rescue workers outside a fire scene, and a reasonable rescue scheme can be made.

Description

technical field [0001] The present invention relates to a comprehensive technology of indoor positioning, navigation, signal processing and the Internet of Things, in particular to a passenger escape indoor navigation system based on building structure diagrams and fire communication systems Background technique [0002] Fire is a serious threat to our life safety. In a fire, especially in densely populated places such as office buildings and hotels, the trapped people often have difficulty escaping because they are not familiar with the environment and the thick smoke in the fire scene. Therefore, it is imminent to realize the positioning and navigation of the trapped people in the fire building. At present, there are not many complete passenger escape navigation systems, such as the following two: [0003] The first is an indoor positioning and escape path planning system for fire rescue proposed by Gao Hongye et al. [1]. The system first uses the WIFI and BlueTooth (Bl...

AI Technical Summary

Problems solved by technology

However, many people cannot choose the optimal escape route due to reasons such as unfamiliarity with the environment, panic, etc., especially in hotels, office buildings, apartments and other places with complex structures and dense population.
